IMPROVEMENT IN CARPENTERS PLOWS.

Specification forming part of Letters Patent No. 97,32, dated l\iovc1nber 30, 1869; antedated NovemberQ-i, 1869.

To all whom t may concern:

` Beit known that I, HARMON VANBUsKIRK, of Vienna, in the county of Genesee and State of Michigan, haveinvented a new and useful ,Improvement in Plow-Planes for Carpenters7 Use; and I do declare that the following is a true andacurate description thereof, reference being hadto the accompanying drawings, andl to the letters of reference marked thereon, and being a part of this specication.

The nature of this invention relates to an improvement in the construction of plow-planes for the use of carpenters and joiners, by means of which the implement may be set for use more accurately and readily than when constructed in the ordinary manner; and it consists in the employment of a right-and-left-hand screw, and a suitable guide, and arms secured to said guide and passing through the stock.

In the drawings, A represents the stock, and B the guide,which are both constructed in the usual manner.

C are thearms, rigidly secured at one end to the guide,while the opposite ends are inserted into and pass through proper holes through the stock,which holes should be of the size of the arms, allowing them to slide freely through said holes without play.

D is a right-and-left hand screw, provided with small hand-wheel a in its longitudinal center. Suitable female screws are cut through the' body A and guide B, which engage withy The right-and-lefthand screw may be made' of wood or metal, as may be most desirable.

In plow-planes of the usual construction the arms are both provided with suitable sc rew threads and nuts, rendering it necessary for the operator to adjust both ends of the implement separately, requiring considerable skill and time. Vith my improvement the proper set is obtained by the one screw, and the operator saves time and trouble.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The right-andlefthand screw D, when used in the construction of carpenters plowlplanes, as herein described, in combination with stock A and guide B, all operating substantially as herein set forth. f
